Update doc glob to look in project root directory

[ghost]

In response to #253:

The error in this issue appears to happen here, where the neovim-dot-app docs are added to the nvim docs within the built app (build/Neovim.app/Contents/Resources/runtime/doc). This error is only encountered on clean builds, and not on subsequent builds.

While not well versed in scons, it seems that this is caused by this line. Based on my research, the VariantDirectory is only set when the build dir does not yet exist. It seems this causes the doc install to look relative to this directory, and errors since all of the doc files are already present. The fix was to look up one directory from the build dir, which would be the project root, and here the doc dir can be found and its files can be written. On subsequent builds, the VariantDir is not set, the doc dir is located in the project root and everything succeeds again.

There might be a better way to do this according to scons best practices, but this is how I got it to work.

I don't know much about scons either but I don't think this does what @rogual intended. I think the nvim_dot_app.txt is supposed to be copied into the neovim docs dir. This doesn't appear to be copied after running make:

git/neovim-dot-app ‹master*› » find . -name "nvim*.txt"
./build/Neovim.app/Contents/Resources/runtime/doc/nvim.txt
./build/Neovim.app/Contents/Resources/runtime/doc/nvim_clipboard.txt
./build/Neovim.app/Contents/Resources/runtime/doc/nvim_from_vim.txt
./build/Neovim.app/Contents/Resources/runtime/doc/nvim_provider.txt
./build/Neovim.app/Contents/Resources/runtime/doc/nvim_python.txt
./build/Neovim.app/Contents/Resources/runtime/doc/nvim_terminal_emulator.txt
./doc/nvim_dot_app.txt

Thanks, but this wasn't the right fix. Fixed in https://github.com/rogual/neovim-dot-app/commit/82b83845a131ea19dd86d9d018cebec4df7b4fc6.
